FerasI think that your problem probably has more to do with the Layout you're using (or not using) than it does with individual column sizes. What layout are you using?
What happens when you set the size (or preferredSize, minimumSize, and maximumSize) on the whole JTable?
You might also be looking for JTable.[getColumnModel()|http://download-llnw.oracle.com/javase/6/docs/api/javax/swing/JTable.html#getColumnModel%28%29].[getColumn()|http://download-llnw.oracle.com/javase/6/docs/api/javax/swing/table/TableColumnModel.html#getColumn%28int%29].[setPreferredWidth()|http://download-llnw.oracle.com/javase/6/docs/api/javax/swing/table/TableColumn.html#setPreferredWidth%28int%29].
If none of those approaches work, post an SSCCE that demonstrates the problem.

Set JTable column width

Hi,
I would like to set the column width of JTable.
========================================
JTable table;
DefaultTableModel tableModel;
tableModel = new DefaultTableModel();
table = new JTable( tableModel);
JScrollPane scrollPane = new JScrollPane(table);
for(int i = 0; i < heading.length; i++)
tableModel.addColumn( heading[ i ]);
========================================

Did you run the tutorial code? Did it work?
Now compare the tutorial code with your code to determine what is different.
We can't tell you what is different based on the one line of code you posted:
colModel.getColumn(i).setPreferredWidth(100);

How to set JTable column's color?

How can I set JTable Columns' color? I only found this class DefaultTableCellRenderer
which can set cell's color.

rmalina wrote:
You are going to need to derive a renderer class for your Column from DefaultTableCellRenderer and override the following function with something like this:
@Override
public Component getTableCellRendererComponent(JTable jTable, Object oValue, boolean isSelected, boolean hasFocus, int nRow, int nColumn) {
super.setForeground(Color.GREEN);
super.setBackground(Color.GREEN);
}That would set your column to green.

How to set the column width of JTable

I want do remember the column width and write it to a file, when the window is started , the column width is read from the file and the table is set as that. I also want the column width is not fixed and can be changed by mouse.But I am always failded.
How to do? would you please help me!
Thanks a lots.

To "remember" the column widths, add a mouse listener to the table header. Upon mouseReleased(), get the column widths and save them to your file. When the application starts next time, get the stored widths and set them using:
table.getColumn("XXX").setPreferredWidth(...);
By default, your columns are adjustable, but you can use:
table.getTableHeader().setResizingAllowed(true);

How to set initial column widths for a table

What I'd like to do is to control the initial column widths for a table.
I'm building the table by using a class which extends AbstractTableModel. This class takes care of setting the headers and reading the data for the table.
If I do the following:
VarTableModel vtm = new VarTableModel(vi);
JTable jt = new JTable(vtm);
JScrollPane jsp = new JScrollPane(jt);
frame.getContentPane().add(jsp);
frame.setVisible(true);
I will see a table in my window. The widths of the columns are equal and are a function of the horizontal dimension of the window.
I have tried to set the width of a column by doing the following:
TableColumn aColumn;
aColumn = jt.getColumn(vtm.getColumnName(0));
aColumn.setWidth(40);
But this has no effect on what gets displayed. I can force the widths that I want by using 'setMaxWidth' but this has the unfortunate side effect of not allowing the user to make the column wider if they want.
What I'd like is a way to specify the widths of the columns when initially displayed and then let the user adjust to their liking.
I'm sure that there is a way to do this, but I don't seem to understand where to intervene in the process to produce the effect that I want.
Any help or suggestions will be greatly appreciated!

Table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
add this line and try ur codeThanks for the suggestion! Unfortunately, it doesn't seem to do the trick. Here is an abbreviated segment of my code:
vtm = new VarTableModel(vi);
JTable jt = new JTable(vtm);
// we want a horizontal scrollbar, so turn resizing off
// and we want to control column widths
jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
aColumn = jt.getColumn(vtm.getColumnName(0));
aColumn.setWidth(40);
. // same kind of thing for each column
aColumn = jt.getColumn(vtm.getColumnName(4));
aColumn.setWidth(400);
JScrollPane jsp = new JScrollPane(jt);
frame.getContentPane().add(jsp);
frame.setVisible(true);
If I do the above, the table gets displayed with each of the five columns the exact same width. So, the sizing of the columns is happening somewhere else despite turning auto resizing off.
Where is that occurring and how can I intervene so that I can control the widths of the columns on initial display and still allow the user to adjust the widths if they so choose?

How to size JTable Column width?? Need help

Using the following logic to size column width, but only the 1st column is sized. How can I get the other columns sized??
int widthsSummary[] = {340,60,150,60,60};
for (int i=0; i<1; i++)
column = getScrollPaneTableSummary).getColumnModel ().getColumn(i);
column.setMinWidth(widthsSummary);
column.setMaxWidth(widthsSummary[i]+50);
column.setPreferredWidth(widthsSummary[i]);

First, take a look at your for loop
for (int i=0; i<1; i++)i starts at 0 and cannot be equal to or greater than 1. This loop will only occur once, when i = 0.
Second, take a look at your set...Width calls
column.setMinWidth(widthsSummary);
column.setMaxWidth(widthsSummary+50);
column.setPreferredWidth(widthsSummary); widthsSummary is an array. You need a number to set widths. Try ...set...width(widthsSummary);
Hope that helps.

How to set dynamic column width for analysis item

Dear Experts,
I have a query view which is added in the web template as an analysis item. The web item properties on width is not working - I tried entering a value in the width but when I execute the template, the query view's width still stays the same.
Module com.sap.ip.bi.rig.ColumnWidth don't seem correct because I don't want the column width to be static. As my number of columns may change, I wanted the overall width of my query view to stay the same.
Appreciate any ideas which can solve this issue
Thanks and Regards,
huimin
BW newbie

Hi Huimin,
I don't think it is possible to fix the width of the Analysis webitem since it dynamically adjusts its width based on the text maxlength within its cells. Unless you use com.sap.ip.bi.rig.ColumnWidth where the cols are static, you cannot achieve this.
Even if you do override the css settings using a cell padding or something, the portal settings would override the same. How about using a Report webitem to insert tables/charts & check if the width can be adjusted here - just a thought.

How to set the column width in the PDF exports of interactive reports ?

Hello,
I have a huge problem with the PDF export for the Interactive reports. I'm using APEX 3.2.
I have to produce a PDF report in landscape format that show 21 columns. My problem is that the columns have a ridiculous short width and that the text inside the columns do not wrap in the columns. So I get things like that :
Date Name
2011 Leina
I should see 2011-08-01 and the name Leinad Jan
I tried several things to format the columns, but none of the them has any effect on the PDF itself.
1) I used HTML code in the report query. It works well with the interactive report, but display the HTML tags in the PDF.
2) I used css to set the width of my columns. It works in the interactive report, but not in the PDF, the column width do not change.
It's like the report do not notice that my page format is Legal 14 x 8.5 (Landscape) and still believe it's 8.5 x 11 (which is "portrait")
Do you have any idea so set the columkn widths in the reports ?
Thank you !

How to set equal column width?

In one report I have 5 tables with different number of rows etc. Is there any possibility or way to make columns inside of it equal? Problem is when report is being exported to .XLS file there are columns which are not visible or sometimes they are merged.
Is there any quick way to avoid it or they only way is to sit in front of SSRS report few hours and somehow manage to set it manually praying that it will be good?

Hi glaeran,
The Excel renderer is primarily a layout renderer. Its goal is to replicate the layout of the rendered report as closely as possibly in an Excel worksheet and consequently cells might be merged in the worksheet to preserve the report layout. As per my understanding,
this behavior is currently by design. For more information about it, please refer to the link below to see merge cells section:
http://msdn.microsoft.com/en-us/library/dd255234.aspx
To avoid the merged cells, if we want to display multiple tables horizontally, the rows of the two tables must be aligned horizontally strictly. If we want to display multiple tables vertically, then the columns of the tables must be aligned vertically strictly.
The following thread about the similar issue is for your reference:
http://social.msdn.microsoft.com/Forums/sqlserver/en-US/7fbb3d31-fc1b-4c9b-8a7d-afc76cbb0291/ssrs-2012-report-export-to-excel-and-sort-thje-data-on-excel-spreadsheet?forum=sqlreportingservices
Hope it helps.

Well I do realise the point of "avoiding merged cells" however the points was to find a simply way to avoid it not just a summary "why SSRS report is behaving this way not another". Hoped that there's somekind of solution for my problem since in one report
as it was said I had to put 5 different tables and every time the report itself is exported to XLS file.. So I thought that maybe it's possible to set same align of cells using table/column/cell properties or whatever so I won't have to spend whole day trying
to match align of 5 tables column by column.. :)

Setting the jTable column width

Coming from VB6 to Java is hard for me. Syntax is so much different.
Below is what I am doing to populate the jTable and the values are coming from MySQL. My problem is setting the column width but I am having difficult understanding how to do it. I looked on the website and downloaded some examples and clearly because I am new and I simply do not understand it. I was wonder if someone is willing to modify the codes below on how I should do it. Thanks
private void populate_grid(){
Vector dataVector = new Vector();
Vector columnVector = new Vector();
columnVector.add("ID#");
columnVector.add("Account Description");
columnVector.add("Contact");
columnVector.add("State");
while (myResult.next()) {
Vector rowVector = new Vector();
System.out.println(myResult.getString("acct_name"));
rowVector.add(myResult.getString("cust_id"));
rowVector.add(myResult.getString("acct_name"));
rowVector.add(myResult.getString("main_contact"));
rowVector.add(myResult.getString("main_state"));
dataVector.add(rowVector);
jTable1.setModel(new javax.swing.table.DefaultTableModel(dataVector, columnVector));

    int rows = 3;
    int cols = 3;
    JTable table = new JTable(rows, cols);
    // Disable auto resizing
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    // Set the first visible column to 100 pixels wide
    int vColIndex = 0;
    TableColumn col = table.getColumnModel().getColumn(vColIndex);
    int width = 100;
    col.setPreferredWidth(width);

Can't set custom column widths in JTable

I'm trying to set custom columns widths. They are set as I wish but then they are reset to default values (all columns have the same size). This is caused by method JFrame.setVisible(true) which invokes JTree.setWidthsFromPreferredWidths(). It can be investigated from following stack trace printed when a column being resized (see below).
How to prevent this auto width sizing?
P.S. can't override JTable.setWidthsFromPreferredWidths(); seems it's private

When I create the table I have code like this:TableColumn col = getColumnModel().getColumn(2);
col.setMinWidth(width + 4);
col.setMaxWidth((int)(width * 1.2));Works just fine for me. The setWidthsFromPreferredWidths() method will use these limits as far as I can see.

}

And after one column added the previous one width is become small(about 75).The model.addColumn() method causes a fireTableStructureChanged event to be generated which causes the TableColumns to be recreated and therefore they default back to their default sizes.
So you need to prevent the columns from being recreated. You do this by adding:
JTable table = new JTable(....);
table.setAutoCreateColumnsFromModel(false);But now you are responsible for adding table columns to the table manually. So your code would be something like;
int index = model.getColumnCount();
model.addColumn(...);
TableColumn tc = new TableColumn(index);
tc.setHeaderValue("" + index);
table.addColumn( tc );
